Answer:
Only active transport requires ATP
Explanation:
Passive transport is the movement of molecules across the cell membrane without the need for energy. These substances usually move from a high concentration to a low concentration.
Active transport relies on energy from ATP to move substances across the plasma membrane. This is usually required when moving substances against their concentration gradient.

Moving up the food chain, the energy available to the organisms decreases due to metabolic heat. (You can add the second law of thermodynamics into it, if you want)
For example, in the rules of tens, the plants start with 100% of the energy but the fi red t level consumers gain 90% of the energy due to the fact energy transfers through heat.
Because of the change is available energy, consumers at the higher levels of the food chain are forced to hunt larger amounts of prey to sub stain themselves.

Which of the following processes is most likely to occur as a result of an
animal cell receiving a signal to initiate apoptosis?
Answers
Answer: lysosomes will release digestive enzymes into the cytosol
Explanation:
Apoptosis is one of the cellular mechanisms of cell death in a controlled manner. At the initiation of apoptosis, the lysosomes start secreting the digestive enzymes in the cytoplasm. Thus, option D is correct.
What is apoptosis?Apoptosis has been defined as programmed cell death in multicellular eukaryotes. It involves biochemical steps that involve cell shrinking, fragmentation of the nucleus, condensation of chromatin structure, decay of the mRNA, and the disintegration of the DNA.
It is a significant process in animal cells as it destroys the unwanted and harmful cancerous cells that can damage the body. They are very crucial in cancer and are initiated by the alteration in the survival signals and sudden dissociations.
The lysosomes play an important role in apoptosis as they're the specialized organs that release digestive enzymes that initiate cell death. They undergo autolysis when the signals for apoptosis are initiated.
Therefore, in option D. the lysosomes are responsible for apoptosis.

Who do the hurricane hunters give data to?
A) National weather service in Miami Florida
B) National hurricane center in Norman Oklahoma
C) National Hurricane Center, in Miami Florida
D) National weather service in Norman Oklahoma
Answers
Answer:
C) National Hurricane Center, in Miami Florida
Explanation:
"Hurricane hunters" refer to people who gather data about tropical cyclones by actually flying into them. This allows them to obtain the actual barometric pressure of hurricanes, including the wind flow speed. The data gathered are then sent to the "National Hurricane Center," which is located in Miami Florida. It has the mission to analyze dangerous storms in order to save many lives by warning people and providing weather forecasts. They also monitor those locations with disturbed weather conditions.
Hurricane hunters give data National Hurricane Center, in Miami Florida. The correct option is C.
Thus, The National Hurricane Centre (NHC), located near Miami, Florida, receives the majority of the data collected by the U.S. Air Force and NOAA (National Oceanic and Atmospheric Administration) aircraft known as the "Hurricane Hunters" as they fly into hurricanes.
Tropical storms and hurricanes in the Atlantic and Eastern Pacific basins must be tracked and forecast by the NHC.
Meteorologists at the NHC use the data gathered by the Hurricane Hunters to enhance hurricane track and intensity forecasts.
Thus, Hurricane hunters give data National Hurricane Center, in Miami Florida. The correct option is C.

C. An increase in the variety of mammals on Earth
D. The extinction of mammals and the rise of insects as the dominant species
Answers
B. Anwar
global warming has a bearing on the planet's biological evolution.
Evolution is the million years old process, which has led to the adaptation and development of a variety of species. The new era of the Earth can be marked by the extinction of mammals and the rise of insects.
The correct option is:
Option D. The extinction of mammals and the rise of insects as the dominant species
The Cretaceous period was ended around 66 million years ago. The sudden asteroid attack on the Earth killed the mass population of mammals and most of all the other species.
Somehow, few of the mammals survived and thrived, which made them dominant across the planet.
In the future, the million years or the hitting of an asteroid can mark the new beginning of an era. The asteroid hitting can lead to the extinction of organisms present on the Earth. Some of the species or insects can survive hypothetically, which can represent the beginning of the new era.
Therefore, the correct option is D.

Answer:
b. Twenty-five percent of the active ingredients in cancer drugs are exclusively rainforest plants.
Explanation:
Rainforest is one of the major biomes on the Earth as it is characterized by high humidity, rainfall and temperature. The rainforest contains a variety of vegetation (plant species) with different economic benefits. According to this question, rainforest plants are being described to be used as anticancer drugs.
However, the statement in the question suggests that the rainforest plants are being used already. Hence, the evidence that describes the use of rainforest plants as anticancer drugs is: Twenty-five percent of the active ingredients in cancer drugs are exclusively rainforest plants. This suggests that 25% of rainforest plants are being used already.
b. Twenty-five percent of the active ingredients in cancer drugs are exclusively rainforest plants.
Anticancer DrugsAny drug that is effective in the treatment of malignant, or cancerous, disease is known as an anticancer drug, also known as antineoplastic drug.

Explanation:
active transport requires energy (atp) to push a molecule agnst its concentration gradient
also glucose molecules r too large to cross without the help of transmembrane proteins
and oxygen molecules r able to get thru by simple diffusion bc they r small enough
Glucose molecules move against the concentration gradient across the cell membrane with the help of ATP is an example of active transport.
Active transport is a biological term to refer to the movement within the cell in which some molecules move across the cell membrane. This movement requires energy from cells to move.
According to the above, when a glucose molecule moves against the concentration gradient across the cell membrane and in this movement it consumes energy (ATP) it is carrying out active transport.

The molecule BPG binds to the deoxy form of hemoglobin in the central cavity. Explain why that makes sense for oxygen delivery and why BPG is said to stabilize the deoxy state.
Answers
Answer:
Oxygen binds with the hemoglobin to carry the blood to different body parts through the circulatory system. The binding of the oxygen to Hb is regulated by the Bisphosphoglycerate or BPG molecule. It is bounded to the deoxy form of hemoglobin.
BPG binds with deoxy Hb in the central cavity of the four subunits which decreases the affinity to hemoglobin. The binding of BPG stabilizes T form or deoxy-Hb as the central cavity is larger in T form in comparison to the R state. R state has a low affinity to oxygen due to relatively smaller central cavity.
Explain how the energy harvested by the electron transport chain is utilized to make ATP and NADPH.

Which was Charles Darwin’s contribution to the study of biology?

He believed that organisms adapted through the inheritance of acquired traits.
He explained how traits are passed from parents to offspring.
He proposed that natural selection is the primary mechanism of evolution.
Answers
Answer:
d
Explanation:
Charles Darwin proposed that natural selection is the primary mechanism of evolution. The correct option is D.
What is natural selection?Natural selection is the method by which living organism populations adapt and change.
Individuals in a population are innately variable, which means they diverge in the some ways. This variation indicates that some people have traits that are better adapted to their surroundings than others.
Natural selection, Darwin proposed, is a mechanism for evolution in which heritable traits that help support life reproduce and survive are becoming more prevalent in a population over time.
Natural selection occurs when genes that confer a survival or reproductive advantage are handed down and persist in a population, whereas genes that result in lower survival or fewer offspring are becoming less common.
Thus, the correct option is A.
